摘要
论文在论述数字水印应用面临的攻击和DHWM协议存在安全隐患的基础上,提出了一种新的基于数字签名的安全数字水印协议。该协议引入数字证书,将数字签名、时间戳和水印信息一起嵌入到数字图像中。通过安全性分析和性能分析,该协议能抵抗中间人攻击、解释攻击,并能检测数字图像是否被非法篡改,可实际应用于数字图像的版权保护。
A new secure watermarking protocol which is based on digital signature is proposed through discussing about the attack over watermarking and the security leak of DHWM protocol.The new protocol imports certificate,and embeds signature,timestamp,watermarking information into digital image.By security analysing and performance analysing,it proves that the protocol can resist the middle-man attack ,the interpreting attack.And it can detect whether the digital image is modified illegally.The new protocol will be applied to copyright protection of digital image.
